Game in which a girl holds a bat awkwardly (7)
I believe the answer is:
netball
'game' is the definition.
(netball is a kind of game)
'a girl holds a bat awkwardly' is the wordplay.
'a girl' becomes 'nell' (I've seen this before**).
'holds' is an insertion indicator.
'awkwardly' is an anagram indicator.
'bat' with letters rearranged gives 'tba'.
'nell' placed around 'tba' is 'NETBALL'.
'in which' acts as a link.
(Other definitions for netball that I've seen before include "Team game/sport" , "Sport whose players wear bibs" , "activity no longer associated solely with girls" , "Seven-a-side team game -- all bent (anag)" , "After this, you get to serve again" .)
